Zhuji, Zhejiang — since 2008
MHOT is the export brand of Zhuji Yangda Auto Maintenance Tools Co., Ltd. The plant runs two production lines for cooling system tools, wheel service equipment and A/C service tools, with assembly, inspection and packing all in house.
That layout is what makes own-brand work practical: logo, case, accessory set and manual are assembled for your order instead of being repacked from somebody else's stock.

What is under our roof
No third-party assembly between your order and the container.
Two production lines
Cooling system and wheel/A-C service tools, running in parallel so one family does not wait for the other.
Assembly & tooling
Presses, sealing and assembly stations for couplers, adapters and kit cases.
In-house inspection
Final inspection and packing, with records kept by order number.
Packing & carton marking
Own-brand cartons, manuals and shipping marks prepared on site for container loading.
Plan a visit
Distributors and brand owners are welcome at the line — seeing a sample on a desk is not the same as watching it come off the line.
